Dangers of Sun Exposure

Skin Damage

Exposure to invisible UV radiation from the sun for long periods of time can cause damage to your skin cells, resulting in a burn. Though UVA rays are more associated with aging skin while UVB rays are associated with burning skin, both types can contribute to sunburns. Here, we will explain the stages and types of sunburn and the risks associated with sunburn, as well as how to treat your burns, should you get any. Please visit our Sunscreen Recommendations page for information on sunscreen in order to prevent burns before they happen.

First Degree Sunburn

First degree sunburns effect the surface layers of the skin; these are the least severe type.

Second Degree Sunburn

Second degree sunburns reach the dermis, where they can begin to damage hair follicles, sweat glands, nerves, blood vessels, and more.

Third Degree Sunburn

Third degree sunburns reach all the way to the hypodermis, causing much more severe damage to nerves and fat tissue.
